Green Diamond’s sands contain no free silica, eliminating the risk of respiratory silicosis, making this a product that is safe for those who handle it. Green Diamond products are also proven to be environmentally safe. This combined with its inherent properties of hardness and durability makes Green Diamond’s sand one that will not only perform well, but will also treat you and the environment in a safe healthy manner.
Green Diamond’s Ferrous and Non-Ferrous Foundry sands have low thermal conductivity resulting in less chilling than silica or olivine sands, allowing the pouring temperature to be reduced. The low thermal expansion reduces the need for cushioning additives or combustibles. It is a tough grain that breaks down very little in use and is environmentally friendly.
